I don't stan any actor or actress. I watch a drama or movie, then move on to the next. I rate every title fairly. 

Technical stuff like lighting, costume, cgi, etc I give more grace to low budget/short dramas. While those should be a given for high budget/full dramas.

And I'm good with any types of endings, happy, tragic or open as long as it has one. I prefer my dramas with a beginning and an end.
